100259 divided by 85 
We want to figure out the number of times 100259 can be divided by 85.

On to step 1:
85 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 85

Step 2:
10 divided by 85 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 85

On to step 3:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 85 from 100 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 85

Step 4:
152 divided by 85 is 1 with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 85 from 152 and we're left with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 85

Step 5:
The number 85 fits into 675 7 times, leaving a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 117.0
If we take 595 away from 675, we end up with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 85

On to step 6:
When dividing 809 by 85, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 1179.0
The remainder is 44 after subtracting 765 from 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
When dividing 440 by 85, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1179.5
Subtract 425 from 440 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 85, we get 1 and a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1179.51
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
650 divided by 85 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 1179.517
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
If we divide 550 by 85, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 1179.5176
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
85 can be fit into 400 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1179.51764
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
85 can be fit into 600 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 1179.517647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
85 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1179.517647
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
If we divide 500 by 85, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 1179.51764705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 1179.51764705 with a remaining 7.5e-08.
